Organisers say 15th-ranked Gael Monfils of France has withdrawn from Wimbledon due to a knee injury.

On the women’s side, Michaella Krajicek of the Netherlands has also pulled out due a viral illness, organisers said in a statement Wednesday.

Monfils also pulled out of the French Open last month because of a knee injury.

Top-ranked Novak Djokovic heads the men’s seedings at Wimbledon, and Maria Sharapova tops the women’s seedings for the first time.

The tournament starts on Monday.
